Answer

Brief Explanations:

Metamorphism is the transformation of existing rock - types (minerals) in a solid - state due to high temperature, pressure, or chemically active fluids. Option A correctly defines it. Minerals are naturally occurring, inorganic substances with a definite chemical composition and a characteristic crystal structure. All options in Question 9 describe properties of minerals.

Answer:

Question 8: A. The process by which new minerals form from existing minerals as a result of elevated temperature or pressure Question 9: None of the above (as all options describe minerals)
